1. ABOUT THIS RELEASE
 
The current update for the Virtuozzo Containers 4.6 kernel provides a new
kernel based on the Red Hat 5.5 kernel (2.6.18-194.26.1.el5). The updated
kernel includes support for fedora-14 OS template and a set of security
and stability fixes
 
--------------------------------------------------------------------------------
 
2. UPDATES DESCRIPTION
 
This update contains fixes for the following issues:
 
* Container on Fedora-14 OS template doesn't work
 
* It is impossible to create a cache of the ubuntu-10.10-x86 EZ template.
 
* The iotop utility does not work in Containers running Ubuntu 10.10 and
  Fedora 13.
 
* Sometimes, the shmpages resource can uncharge too many pages.
 
* The /proc/bc/<id>/meminfo file needs to be added to the /proc system.
 
* An inotify/inode mutex deadlock may occur in Containers running KDE 4.1.3 or
  4.2.
 
* Some files may get lost after migrating Containers with NFS shares mounted.
 
* Running the bonnie++ application simultaneously in several Containers and
  setting the I/O limit for these Containers later may lead to the termination
  of bonnie++ and the inability to stop the affected Containers.
